Grumble. Now I'm not sure why -- I thought* perhaps incorrectly?? that SSH key pairs were server agnostic. That is, I thought/assumed that if my public/private key work on server A they'll work on server B. Apparently that is not the case and at the moment I have no clue why. So not a perl problem, which I might have had a chance of dealing with, but SSH key exchange problem about which I have no clue. Off to try to understand it.. Sorry to think this is a Perl problem... /Bernie\	[reply]

Problem solved! A unix-friend made a suggestion that proved to be correct: the authorized_keys file has to be non-writable. I had just copied in the key so it got some default protections. chmod 710 did the trick. Sorry to bother you guys...	[reply]
